DOOR-CHECK..

SPECIFICATION forming part of Letters Patent No. 446,322, dated February10, 1891.

Application filed October 18, 1890. Serial No. 368,546. (No model.)

To all whom it may concern:

Be it known'th at I, LEE ELIsHA CALDWELL, a citizen of the UnitedStates, and a resident of Elvaston, in the county of Hancock and Stateof Illinois, have invented certain new and useful Improvements inDoor-Checks; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon,whieh form a part of this specification.

Figure 1 of the drawings is a representation of the invention asapplied, and Fig. 2 is a side view.

This invention has relation to cheeks or stops for doors, gates, rbc.;and it consists in the novel construction and combination of the parts,as hereinafter set forth.

In the accompanying drawings, theletter A designates the jamb-piece, andB the door piece, said pieces constituting the check or stop. Thesepieces are formed from angular sheets of spring metal, consisting ofperforated Vertical bases c, for attachment, respectively, to the faceof the door jamb or post and to the door D, as shown: Proceedinghorizontally from the bases c are tongues E, having concave-convex ordished extremities fand g stamped in the metal. The concavity fof thejamb-piece A is surrounded by an outwardly and downwardly flaring beador rim h in order to present an oval face to the convexity of dished endg of the doorpieee B, and Vin order to permit said end to rise over andsettle back within the eoncavity f of the jamb-piece when the door isopened. The dished end g is unlike dishf, in that it does not possessthe Haring rim. As the dishes of the two check-pieces are nested whenthe door is opened, the pressure of the two against each other issufficient to hold the door owing to the elasticity of the metal; yetthey may be detached in closing the door by the exerfr oise of a littleforce upon the latter.

This check may be made in different sizes and of metal of dilerentdegrees of elasticity or tension according to the weight of the door towhich they apply.

hat I claim as my invention, and desire to secureby Letters Patent, is-

l. A door-check comprising two elastic angular pieces of metal secured,respectively, to the door and jamb and provided at their outer meetingextremities with concavo convex locking ends, substantially asspecified.

2. A door-check comprising the angular check-pieces A and B, havingperforated bases Gand concave-convex locking ends, one of said endsbeing provided around its convexity with an annular oval bead or rim hfor adapting it to receive the convexity of the opposite cheek-piece B,substantially as shown and described. y

In testimony whereof I aix my signature in presence of two witnesses.

LEE ELISIIA CALDWELL.
